Description

Summary

The Primary objective is to demonstrate the efficacy of dupilumab treatment compared with placebo in pediatric patients with active eosinophilic esophagitis (EoE) based on histologic improvement meeting validated histologic criteria. The Secondary objectives are: - To demonstrate the efficacy of dupilumab compared to placebo in pediatric patients with active EoE after 16 weeks of treatment as assessed by endoscopic visual measurements of disease activity using the Eosinophilic Esophagitis-Endoscopic Reference Score (EoE-EREFS) and histologic abnormalities as measured by the EoE Histology Scoring System (EoE-HSS) - To evaluate the safety, tolerability, and immunogenicity of dupilumab treatment for up to 16 weeks in pediatric patients with active EoE - To evaluate the effects of dupilumab on transcriptomic signatures associated with EoE and type 2 inflammation - To study the effects of dupilumab on the type 2 inflammation gene expression signature - To evaluate the concentration-time profile of functional dupilumab in serum in this population - To assess efficacy of long-term (52 weeks) dupilumab treatment - To assess safety, tolerability, and immunogenicity of long-term (52 weeks) dupilumab treatment - To evaluate the impact of dupilumab treatment on EoE signs and symptoms

Eligibility

You can join if…

Open to people ages 1-11

  • A documented diagnosis of eosinophilic esophagitis (EoE)
  • Baseline endoscopic biopsies with a demonstration on central reading of intraepithelial eosinophilic infiltration

You CAN'T join if...

  • Body weight <5 kg or ≥60 kg at screening
  • Other causes of esophageal eosinophilia
  • Active Helicobacter pylori
  • History of Crohn's disease, ulcerative colitis, celiac disease, or prior esophageal surgery
  • Any esophageal stricture unable to be passed with a standard, diagnostic, upper endoscope or any critical esophageal stricture that requires dilation at screening
  • Treatment with swallowed topical corticosteroids within 8 weeks prior to baseline standard of care endoscopy
  • History of bleeding disorders or esophageal varices that, in the opinion of the investigator, would put the patient at undue risk for significant complications from an endoscopy procedure
  • Active parasitic infection or suspected parasitic infection
  • Known or suspected immunodeficiency disorder
